I won't make it public tho

why not

09:23

Because it's work in progress

09:24

I mean

09:24

I can make it public

09:24

I suppose

omw

Just don't look at it

Because it's work in progress

you dont have to make it public only when its ready

ur malloc is wrong

09:53

u should declare Array2D on the stack and only malloc the data field

09:53

see, u dont understand pointers yet i think

09:53

or well, malloc

literally me pepeW

pepeW

and u dont need a for loop to set everything to 0

09:54

use memset

I know

Ryozuki

ur malloc is wrong

Well i guess

no guess, its wrong xd

I don't rember what i did

09:56

But i think i did a lot of weird stuff (edited)

Ryozuki

u should declare Array2D on the stack and only malloc the data field

I didn't know how to do that i guess

10:06

And I don't know what's wrong with this approach

10:06

It works i think?

10:07

It returns a pointer to Array2D

10:07

Which is what i want

10:07

I do understand pointers

10:07

There is literally nothing confusing about them

10:08

Which doesn't mean it's easy to use them

pilonpl

I didn't know how to do that i guess

Yeah i think it was easier for me to do it this way

10:19

I guess i can change that

10:21

Does it change anything tho?

ScReeNy

Dont forget to use the right winning conditions

I actually forgor to check for ending conditions lol

10:26

The discover function could return different value if you discover a mine

10:26

And for win detection

10:26

Maybe separate function

10:27

I need to check is the number of mines == number of undiscovered tiles

10:28

Flags are purely quality of life feature

pilonpl

It returns a pointer to Array2D

nah u dont want that

Why not

10:30

Too many pointers can't hurt

u want to return a Array2D by value, the field in the struct data, is a pointer

10:30

the thing is u dont even know what ur doing with that malloc

10:30

its better to assume u dont know than assume wrong btw

10:30

im not home but later ill tell u how

10:31

also on the stack it means basically not a pointer, by value

I know

10:32

But

10:32

Returning Array2D by value doesn't change that much really

10:32

On what level is it better? (edited)

it does, stack is always faster, also ur malloc is simply wrong, it works due to u over allocating and cuz the array field is last

10:33

sheer luck

10:33

declare the Array2D by value and point data to a malloc of sizeof int x width x height

The array field is last because it has to be last. The compiler doesn't allow it to be in the middle

i wish there was a language that could manage memory by iteself

ScReeNy

i wish there was a language that could manage memory by iteself

all GC langs do

10:34

java

i expected u to shill rust

pilonpl

The array field is last because it has to be last. The compiler doesn't allow it to be in the middle

nice, C stuff

10:35

it can be on middle if u declare data as a int* btw

Ryozuki

it does, stack is always faster, also ur malloc is simply wrong, it works due to u over allocating and cuz the array field is last

Speed isn't that big of deal even on my shit pc. Am i overallocating? I think it's pretty close to the actual size i need

which is the same rly

10:35

u said u wanted perfection

10:35

but i see ugliness

10:35

xd

10:35

and wrong stuff

10:36

nah ur over allocating by a lot

It is wrong in a sense that it's not optimal

10:36

But it does work technically

its not optimal and wrong

10:36

the malloc is wrong

10:36

u know a program can "work" with Ub right?

10:36

but it doesnt mean its correct

Ub?

10:37

Whats that

undefined behavior

Ryozuki

nah ur over allocating by a lot

width * height * sizeof(int) is what i need for the array, right?

its what u need for the field data

Yes

the other stuff u dont need malloc

If i want to have a pointer to Array2D i need malloc

why u want a ptr to that

10:39

its 3 ints

I can allocate only data and Array2D have as a value

Ryozuki

why u want a ptr to that

Idk, i probably don't want it if i want to be pro

10:41

But it's like my second ever program in C

Array2D* array = malloc(sizeof(Array2D) + width * height * sizeof(int));

10:41

sizeof array2d returns the total size of the struct btw

So i basically made something that works kind of and maybe ill improve it later

it works by luck

Ryozuki

sizeof array2d returns the total size of the struct btw

Right and what is it?

10:41

Tbh idk

10:42

I didn't not check that xd

its the size of each field of array2d together

Right

10:42

So 64 bit for each field

Array2D x; (edited)

10:43

x.width = width

10:43

x.geight = height

10:43

x.data = malloc(sizeof(int) * width * height) (edited)

10:43

return x

10:43

change return type to Array2D

Alright

10:45

This is a better solution i guess

also u need to make a free method

10:45

that frees x.data

It's not like it matters on modern hardware

god damn

10:46

u will just make me not help u at this point

10:46

xd

I want to understand what makes this better

10:47

It might be faster right

ur allocating the correct memory, ur not pointless overallocating on the heap, you free memory u dont need, its how a correct C programmer works

10:47

ask @Learath2

10:48

ur malloc is plain wrong too

What do you mean by wrong

and that u dont see it means u need to learn a lot

It allocates enough memero for the array to fit in

10:49

Maybe even more then enough

10:49

And yeah allocating more memory than needed is technically bad

im done

10:49

ima enjoy dinner

10:49

or launch

10:49

i forgot the name

What do you not understand xd

nono

10:50

what U dont understand

10:50

and ita pointless to convince someone noob that thinks they right

Ryozuki

also u need to make a free method

I don't actually need that because i have a lot of ram xd

Ryozuki

and ita pointless to convince someone noob that thinks they right

But i think you are right

10:51

I just thought you meant my program doesn't work

10:51

Because "wrong" kind of implies that

ur program shows a output u expect by luck

10:52

its not correct

How is that luck?

u can achieve a result by not knowing much what u are doing and think its correct, but a correct program entails more than just a output

10:54

anyway its not just that method

I know how much memory i need. I need height * width * sizeof(int) for the data and since i currently allocate the whole Array2D using malloc i need additional sizeof(Array2D)

the whole Array2D shows u dont know what u doing

So i guess its better to return Array2D by value

10:55

Right?

yes

I agree with that

u confuse where u need a pointer

10:55

data is the only ptr u need

Yes

10:55

I know

data[] is equivalent to *data

1

But i can create a pointer to whatever i want

Ryozuki

data[] is equivalent to *data

I know about that

but u never point data

10:56

to anywhere

10:56

thata why i say it works by luck

10:56

i think its UB

pilonpl

But i can create a pointer to whatever i want

So i created a pointer to Array2D and even if it's not a good thing to do it doesn't break anything. I just need to use array->field or (*array).field

the pointer u created with malloc also overallocates

10:57

u only need sizeof(Array2D)

10:57

for a ptr to Array2D

Hmmm

10:58

Oh i think i see what you mean

and u need to point data to somewhere

10:58

that somewhere is a ptr returned by allocating with malloc

10:58

there is where u use the width and height and size of int

I understand how malloc works mostly and how pointers work but I don't know how incomplete types work

so if for some reason unwant Array2D as a ptr

10:59

u need 2 mallocs

10:59

there is no incomplete type here

10:59

ur not forward declaring anything

Is it not an incomplete type? That's what the compiler said as far as i remember correctly

pilonpl

I understand how malloc works mostly and how pointers work but I don't know how incomplete types work

u dont based on the code u sent

11:00

dont lie to urself

11:00

its ok, just learn

I mean

11:01

I don't understand a lot of things

yeah and that's fine

But pointers and malloc in theory i know how work

...

11:01

anyway

I don't know how to use them in practice

then u dont rly know them

Pointers are just a memory address and malloc returns a pointer. How is that difficult?

11:02

What i am confused about are these "incomplete types"

11:03

I had a lot of trouble with those

malloc doesnt simply return a pointer

11:03

it allocates a contigous memory region based on the size you give it, aligned properly. then returns a pointer to the start of the region

11:03

the size u pass is wrong

11:04

thus u dont know malloc

Ryozuki

it allocates a contigous memory region based on the size you give it, aligned properly. then returns a pointer to the start of the region

Yeah i know about that. I think?

11:04

I mean obviously it does some magic

not based on the code u sent

Ryozuki

i think its UB

Maybe data is on the same block of memory as Array2d so allocating that much more for array2d also made some space for data?

i cant be a teacher i get annoyed easily xd

11:05

@Chairn how u do this job kek

Devinci

Maybe data is on the same block of memory as Array2d so allocating that much more for array2d also made some space for data?

That's exactly what i thought, it might be wrong tho

11:05

I didn't think much of it because it worked lol

It still looks wrong tho

Devinci

Maybe data is on the same block of memory as Array2d so allocating that much more for array2d also made some space for data?

ye it works here cuz he overallocates i think, but working doesnt mean correct

11:05

ub can "work"

Now i am trying to understand what's wrong but ryozuki just tells me i don't understand anything lol

He kinda explained it but with a bit of salt xd

xd

Ryozuki

ye it works here cuz he overallocates i think, but working doesnt mean correct

Is it actually overallocation when i know i need this memory because that's how C works with these what i think are incomplete types?

@Learath2 help

What's even going on

pilonpl

Is it actually overallocation when i know i need this memory because that's how C works with these what i think are incomplete types?

It is. Just allocate the correct memory for array2d and then allocate for data. Maybe what you did really works but i've never seen it (edited)

What crime did pilonpl commit?

check the code i sent

11:09

i mean maybe this works

Ryozuki

data[] is equivalent to *data

Actually it is you who is wrong this time

Ryozuki

check the code i sent

You tell me i dont understand anything because i am trying to understand what's wrong. That's the issue, i am not trying to argue what i did is "correct" or anything because it probably isn't. It's literally my second program in C ever.

justatest

It's a C99 thing, flexible array member

justatest

So i am not trying to argue against you, i want to understand your point @Ryozuki

i guessed that but i wanted to teach it properly

11:11

he doesnt need Array2D on the heap itself

That data[] there is not a pointer at all, it's an array of unknown size

And i think what i did there is an actual C feature but i am not sure and even if it is I dont argue it's a good practice

But then he uses it withouth ever declaring it's size? Or the array2d malloc somehow gave it the size

Learath2

That data[] there is not a pointer at all, it's an array of unknown size

damned be C and all the hidden stuff

Devinci

But then he uses it withouth ever declaring it's size? Or the array2d malloc somehow gave it the size

I know it's size because i store it in the struct Array2D

Devinci

But then he uses it withouth ever declaring it's size? Or the array2d malloc somehow gave it the size

It has no declared size. Flexible array members are as large as whatever is remaining in the malloc

i see

Learath2

It has no declared size. Flexible array members are as large as whatever is remaining in the malloc

So am i right and this is a feature?

its like a field representing the "remaining memory" after the declared fields

Yes it is an actual feature

Still should use ryozuki's approach

And is it good practice?

but u need pointer indirection to get width height and size (edited)

Ryozuki

its like a field representing the "remaining memory" after the declared fields

Yes, it thus has to always be the last member and you should always keep track of it's size

and the data itself

Oh, so you can't have 2 arrays, data1 and data2 sharing that remaining memory? It's only the last one?

i still believe only data should be on heap

pilonpl

Still should use ryozuki's approach

What did ryozuki suggest? The way you have it is probably better for performance then double indirection

Ryozuki

i still believe only data should be on heap

Yeah, this is how the common pattern is

Array2D by value

11:15

and data as a ptr

11:15

thats what i suggested

But locality probably actually means this solution has better performance. Though hard to know without testing

11:16

This pattern is common in stuff like malloc implementations

11:16

Where you want a transparent header and metadata close

@pilonpl did u know this feature when u made this

Alright so i guess my solution can stay and it's acceptable and ryozuki's solution is good too if not better (that's what I wanted to do originally but didn't for some reason)

Ryozuki

@pilonpl did u know this feature when u made this

Yes because i found this on the internet

anyway my point is getting somehing to work and understanding why it works (and maybe its UB) is different

What UB means? Lol

undefined behavior

And yeah, i understand why it works mostly

Be very careful with UB if you are learning C

Ryozuki

undefined behavior

Oh alright, this is actually defined behaviour i think

and please free ur memory

11:18

good practice

I will

make a hashmap

But honestly buy more ram

11:19

I rely on the os to free the memory

if u dont free memory, the issue comes at hand on long running programs

11:20

u accumulate leaks

It's fine as long as i only have one minesweeper struct

11:20

And that's the case for now

11:20

So

learn rust so u dont deal with Ub

11:20

gigachad

Right

11:21

Learning rust isn't a very good way of learning C

pilonpl

I rely on the os to free the memory

It's good practice to always make sure you free. In library code e.g. you shouldn't rely on the OS

11:21

Or in a freestanding environment

Obviously

11:22

Can i just free(array2d)?

Yes

Nice

Ryozuki

learn rust so u dont deal with Ub

Too chad

C is fun cuz u have lot of control, but easily get lost

11:24

lost deep

11:24

and u may not even know u do smth wrong

~~I am actually surprised i was right after all lol~~

Only like 10 people know flexible array members, I was surprised u knew

So actually i am a pro

monkaStop

11:25

pepeW

I am on a good path to becoming a hacker

make a open addressing hashmap

Kernel has a lot of flexible array members too

and a red black tree

So is everything else ok in the code?

11:34

I think some variable names aren't all that great

11:34

And obviously the discover function could be better

11:37

I don't know how to properly compile a project with raylib tho

11:38

Using only pro tools

11:38

That is command line

11:38

And not a whole ide

11:38

Like visual studio

wow this was a long read, so long even I have forgotten what useless piece of information i wanted to share

Well

11:39

It was kind of a useless conversation too

keep learning, but internet strangers arent always better

@Ryozuki see robyte is a fellow

tv series too

15:50

shinsekai yori is nice

15:50

@Robyt3 have u watched monogatari

Ryozuki

@Robyt3 have u watched monogatari

no

recommended

15:51

watch like this

15:51

Bakemonogatari (2009) Nisemonogatari (2012) Nekomonogatari (2012) Monogatari Series: Second Season (2013) Hanamonogatari (2014) Tsukimonogatari (2014) Owarimonogatari I (2015) Kizumonogatari I: Tekketsu-Hen (2016) Koyomimonogatari (2016) Kizumonogatari II: Nekketsu-Hen (2016) Kizumonogatari III: Reiketsu-Hen (2016) Owarimonogatari II (2017) Zoku Owarimonogatari (2018) (edited)

ah yes, when you need a guide to watch it in the correct order

u know its good then

I think I had it on my list at some point

naah but fr

15:52

it has epic animation, epic plot, and its those that are like misterious and philosophical

15:52

and its rly weeb

15:52

really mahouka koukou is considered good nowdays, god how the mighty have fallen

xddd

15:52

15:52

btw im not attacking robyt but ryozuki with the "good taste"

15:52

as robyt said its his favorites

15:52

so he can favorite anything

I also have the Mahouka novel

15:53

Because I like the technical details about magic programming

is it any better than animation? i remember tatte no yusha narigari? was worst novel i ever read

meh

15:53

tatte no yusha is new

15:53

watch planetes

15:54

15:54

old anime hits diferent fr

im talking novel

15:54

i read novel in 2014?

15:54

or so

Overlord

is it any better than animation? i remember tatte no yusha narigari? was worst novel i ever read

Depends on what you are looking for, I'd say they didn't cut much action from the anime but mostly background and technical information about the world and magic

my favorite anime died

15:54

the last 2 episodes ago

no game no life

15:54

sad we will never see s2

One Piece turned into a cartoon

15:55

for no apparent reason

15:55

(that's no joke)

Ryozuki

no game no life

I also read all of the novels

15:55

Also waiting for season 2 feelsbadman

feelsbadman

@Robyt3 do u read manga

15:56

did u read oyasumi punpun

15:56

No, haven't read much manga

ok

15:56

ur weird weeb

15:56

ln and anime

15:56

but no manga

I rarely read

i havent read ln

15:57

i like the drawings

15:57

boobas u know

15:57

joking

i feel robyte

or not

i never read a book in my entire life XDD

well ppl say manga is not a book

I mostly read in the bus or train so I prefer PDFs

manga is definitly less booky than a LN

15:57
